Answer

Answer

A monoplace chamber compresses one person at a time, usually in a reclining position (see image below). The gas used to pressurize the vessel is usually 100% oxygen. Some chambers have masks available to provide an alternate breathing gas (such as air). Employees tend to the patient from outside of the chamber and equipment remains outside the chamber. Only certain intravenous lines and ventilation ducts penetrate through the hull. Newer Duoplace chambers can hold two people. Their operation is similar to that of a monoplace chamber.
